What are some examples of the stimulus response model in action. Biology coordination and control stimulus response model. A stimulus is a change in the environment either external or internal that is detected by a receptor.
Response the activity of a cell or organism in terms of movement hormone secretion or enzyme production as a result of a stimulus. The role of receptors sensory neurons relay neurons motor neurons synapses and effectors in the response of animals to stimuli are shown in the figure below.
